This rating is not for the quality, which appears to be good.  It's for poor communication about delivery.  We were notified at the time of order to expect delivery the middle of next week, but came home after a day of steady rain to find the boxes sitting outside, soaking wet, four days early.  Fortunately, the inner plastic wrapping protected all but part of one piece, but if only we had gotten notice of shipping or a better estimated receiving date, we could have made other arrangements.  High marks for speedy delivery!  Bad communication!
